Spurious failure trying to checkout the repository

We're experiencing spurious failures trying to checkout repositories on GitHub Actions:

Getting action download info

Contacted GitHub Support on this, I see no way for us to mitigate the problem on our end.

Another failure: https://github.com/rust-lang-ci/rust/runs/1354742853

Another failure: https://github.com/rust-lang-ci/rust/runs/1354742853 (added it to the top comment too).

Enabled debug logging on rust-lang-ci/rust and opened #78754 as recommended by GitHub Support. Once another build fails we'll probably be able to drill down more into the cause. There is also another report of the same issue available at actions/checkout#376.

Following on from your comment in actions/checkout#376 (comment) the worst part about this is that it's impossible to repro this
